Solve: (2.5×0.5)(+1.3×0.3)-(1.4×0.2)
Use the concept of multiplication of decimals
Given (2.5×0.5)(+1.3×0.3)-(1.4×0.2)
Will solve the brackets first, so
(2.5×0.5)(+1.3×0.3)-(1.4×0.2)
=(1.25)(0.39)-(0.28)
According to BODMAS, first off brackets and then multiplication
=(0.4875)-(0.28)=0.2075
Hence, (2.5×0.5)(+1.3×0.3)-(1.4×0.2)=0.2075
